California Gold Slot by Light & Wonder

The Mad Miner Bonus is the part that sets this one apart from the usual line-pays setup. The wild Miner only lands on reels two, three and four, and when he shows up on all three at once the bonus fires. You pick one of four mine shafts, then watch the prospector trudge inside and grab up to five gold nuggets. Each nugget is weighed in ounces, and your payout is the total ounce count multiplied by the bet that triggered the round. Light hits feel modest. A full five-nugget haul on a heavy bet is where the round earns its keep.

Outside the bonus, the Miner doubles any win he completes as a substitute, which stacks neatly with the middle-reel positioning. The scattered gold nugget cluster pays from any position and triggers the free games when three or more land. You get ten spins, every prize tripled, and the feature can re-trigger from inside itself. The Mad Miner pick can also fire mid-free-games, so a tripled base spin plus a nugget haul is the run you want.

Visually it leans hard into comic Wild West. A wide-eyed bearded prospector in a green checked shirt and blue dungarees stands over a cart of gold, shovel slung across one shoulder, against a sunny desert canyon with a carved-out mine entrance, wooden barrels and a coiled rope. The palette is all warm ochre, gold and dusty brown under a bright blue sky. It is an older NextGen design now sitting in the Light & Wonder catalogue, and the cartoon tone is closer to a Saturday morning short than a gritty mining sim. If you like the pick-and-collect setup, the pick bonus here is simple but readable, with the weighing-scale animation doing all the suspense.
